--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
The issue is likely that if-conversion produced a vector loop copy with a
different number of exit edges than the original not if-converted version
because of if-conversion doing simple DCE/FRE/DSE but the reporter disabling
all those opts.
